CASEMENT-HINGE.

Specification of Letters Patent.

Patented June I, 1915.

Application filed May 27, 1914. Serial No. 841,230.

To all whom it may concern Be it known that I, BENJAMIN JOSEPH BROWNJOI-IN, a subject of the King of Great Britain and Ireland, residingat Culwulla Chambers, Castlereagh street, Sydney, New South Wales, Australia, have invented certain new and useful Improvements in Casement-Hinges, of which the following is a specification.

This invention relates to an improved hanging or mounting for middle hung casement sashes, that is to say for casement sashes adapted to be swung on vertical hinges, the pintles of which are located bebetween the stiles and not at either extreme side of the sash.

The invention consists in a certain specifio form of hinge for this purpose constructed so as to be conveniently fitted from within a building, and embodying weather strips to insure weather tightness and a segmental plate in connection with the lower hinge to facilitate the fixing of the sash in a more or less opened position right hand or left hand as required for the purpose of insuring good ventilation. As the hinges operate to allow the sashes to be turned to expose either side outward, cleaning of the glass by a person located within the apartment is facilitated.

In the accompanying drawings, Figure 1 is an external elevational view of a window frame in which a sash is hung with fittings according to the present invention; Fig. 2 is a perspective view taken from the inner side of a frame and casement sash therein hung with fittings according to the present invention, showing the sash fully opened in the frame; Fig. 8 is a broken sectional elevation through the lower part of the frame and fittings showing the sash in the opened position; Fig. 4: is a broken perspective view showing the lower hinge with weather strip and lock segmental plate.

In these drawings, A are the frame stiles, B the sash stiles, C the frame heads, D the frame sills, E the top rails of the sashes, and F the foot rails of the sashes. The sills D are molded according to any standard pattern witha rabbet forming a stop for the foot of the sash. The frame head C is similarly molded with a rabbet to form a stop for the top of the sash. The upper hanger or hinge may be of any suitable form, such as, a leaf C attachable to the top rail E of the sash by means of screws, a pintle joint I-I formmg the mounting of said leaf G on. a butt plate J-j of T-section.

The sash mounting at the foot comprises a leaf K adapted to be screwed to the foot rail of the sash, a pintle mounting L between this leaf K and the butt M, and integral with said butt M a sloping water race N and a segmental plate 0 over which plate the cutaway portion of the sash may swing. The rear portion n of the water race N is nearly flush with the surface of the segmental plate 0 but its forward end n is flush with the runway of the sill D. When the sash is closed, its cutaway portion backward of the pintle L moves clear over the segmental plate 0 and sets hard up against the butt M. Any weather leakage between the sash and the butt M is intercepted in the water race N underlying the foot of the sash and is checked from entering over the plate 0 which is fastened hard down on the top of the sill by screws Q.

Sashes may be hung with these fittings without requiring the carpenter to work outside a building. The frame having been erected in the ordinary way, the head and foot of the sash are cut away in the manner described to accommodate the fittings. The leaves G and K of these fittings being screwed to the sash after preliminary marking ofi, the sash and fittings may be at once lifted into the closed position and the inside screws put in, then the sash is sufficiently opened, then the web of the top butt screwed up to the head of the frame, and lastly the segmental plate 0 carrying the water race N and the butt M is screwed down to the sill of the frame. The sash is fitted with a latch, spring bolt, drop bolt or other fitting adapted to engage holes or serrations in the arc of the segmental plate O for the purpose of fixing the sash set at any angular position right hand or left hand so as to deflect draft and thereby facilitate the ventilation of the apartment in which the window is fitted. The sash may be turned either side out as required to facilitate cleaning.

What I claim as my invention and desire to secure by Letters Patent is 1. A lower hinge mounting for a middle hung casement sash, comprising a leaf attachable to the sash and a butt attachable to the sill, said butt forming a weather strip and rearward thereof below the sash rail a sloping water race and overlying the sash,

dle hung casement sash, a hinge butt depressed below the upper plane of the sash sill, and water race rearward thereof.

3. A hinge mounting for amiddle hung casement sash comprising a leaf and a butt,

whereof the leaf is attachable to the face of the's'ash and the butt to the sash frame, said sash frame having cut away portions, said butt and leaf setting flush in the closed position tight up to the sash face so as to act as a weather strip covering portions of the sash cut away to provide swinging clear ance over the rabbet stop of the frame.

4. A lower mounting hinge for a middle hung casement sash comprising a leaf K, a butt M, and integral with said butt, a water race N and a segmental plate 0 overlying the sill and said plate provided with bolt holes adapted to receive a bolt carried by the sash, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
